There is no tag on the bcgovimages/von-image image called py36-indy1.3.1-dev-441-ew-s2i on docker hub. It might have been removed and replaced with a newer one. I quickly tried finding one that looked like your tag, but didn't have any luck.

I'd try using bcgovimages/von-image:py36-1.16-1 since that's the newest one that starts with py36.

You can check what tags are available here: https://hub.docker.com/r/bcgovimages/von-image/tags?page=1

Most of this is documented in the setup docs, unfortunately nvcr.io doesn't have very good SEO or UX, so search results and most attempts don't show this page. This is, confusingly, different to ngc catalog / docker login ngc.nvidia.com.

• Install NGC CLI: (for macOS)
  • Run curl -O https://ngc.nvidia.com/downloads/ngccli_mac.zip && unzip ngccli_mac.zip && chmod u+x ngc
  • mv ngc /usr/local/bin/ngc
• Setup your environment:
  • Add the API key to the CLI: ngc config set
  • Login to registry: docker login nvcr.io
• Observe docker CLI output containing correct auth details:

so as @Chris Culter mentioned in a comment above, I just restarted my machine and it works again.

It is kind of strange because I already updated my Docker Desktop, restarted, and cleaned/ purged the docker data. None of those helped, just after restarting my windows it works again!

this seems to have resolved itself...

I have this problem too, and via Google I found other people asking about it with no good solution.

My workaround:

1. When I'm still on a good Internet connection I docker pull some_public_image:123.
2. docker tag some_public_image:123 this_is_stupid_but_i_retagged_some_public_image.
3. In my Dockerfile I use FROM this_is_stupid_but_i_retagged_some_public_image.

I wouldn't merge this hack to main but it let me be productive on a long trip.

.NET Core version 2.2 is not supported anymore, the current LTS .NET version is 6.0. You can see the existing image versions of ASP.NET Core runtime on docker hub.

Updating .NET version on your machine:

If you are using Visual Studio you can use the Visual Studio Installer to install .NET 6 and all the templates that come with it. Then you should either recreate your project with .NET version 6, or upgrade you existing projects to .NET 6 and then re-generate your dockerfile, You can generate a Dockerfile in Visual Studio by right clicking the project file --> add --> docker support, before these steps you should delete your existing dockerfile.

Reinstalling docker helped to fix this problem

The error is right in the message - pull access denied. You also have a second issue in your FROM statement in that you aren't specifying the full path the image you linked.

So you have two things to resolve:

1. When you pull from redhat's registry, you'll need to provide the full URL and not just the image name. For the image you linked, that means you need "FROM registry.redhat.io/ubi8/s2i-base:rhel18.5 as Builder`.
2. When you use Redhat's registry, they want you to create a service account and login with it. They provide instructions on how to do this under the "Get This Image" tag, but in short you need to use docker login to login to registry.redhat.io before you run your docker build command.

After you've resolved those issues, you have a third issue in your Dockerfile that you'll need to resolve:

1. You're using the apk package manager to attempt to install packages, which is the package manager for Alpine linux. The image you're attempting to extend uses the yum package manager instead (you can see this in the provided Dockerfile for it), and so will need to use that package manager instead to install your dependencies.

Between those things, your pull access should be authorized correctly, and your build issues resolved.

I had to set DOCKER_BUILDKIT=0 before build command
